Product Features
a. Outstanding Flocculation and Sedimentation Performance
Rapid Flocculation: PAC expertly initiates the formation of compact alum clusters in water, achieving a settling rate that surpasses conventional aluminum salts, like aluminum sulfate, by an impressive 30% to 50%. This remarkable efficiency substantially shortens the treatment process, setting new standards in flocculation speed.
Efficient Turbidity Removal: Boasting an extraordinary ability to eliminate colloidal particles and suspended solids (SS), PAC's remarkable removal efficiency exceeds 95%, resulting in effluent turbidity plummeting to levels below 5NTU. Experience a new echelon of clarity and purity in treated water.
Wide pH Adaptability: With outstanding performance across a wide pH range of 5-9, PAC eliminates the need for constant pH adjustments, simplifying operational procedures and enhancing efficiency.
b. Significant Environmental and Economic Advantages
Low Residue Characteristics: The high-purity formulation (Al2O3 ≥ 28%) reduces sludge volume by 20% to 30%, effectively curbing sludge disposal costs and contributing to more sustainable waste management practices.
Medication Usage Savings: Delivering equivalent results with only 1/2 to 1/3 the dosage of aluminum sulfate, PAC promises substantial long-term cost reductions, surpassing 30% savings.
No Secondary Pollution: PAC ensures the concentration of heavy metals, including lead and others, remains well below national standard thresholds, guaranteeing heightened safety for treated wastewater and upholding environmental standards.
c. Robust Adaptability to Water Quality
Low Temperature Resistance: Exhibiting robust flocculation efficiency in cold environments below 5 ºC, PAC effectively overcomes the challenges posed by reduced sewage treatment efficiency during harsh winter periods.
High Turbidity Tolerance: Designed to handle high turbidity wastewater with SS concentrations up to 5000mg/L, PAC excels in challenging scenarios such as ore washing and construction mud water, maintaining superior performance.
Synergistic Effect Enhancement: In conjunction with polyacrylamide (PAM), PAC amplifies flocculation strength and dewatering efficacy, making it exceptionally suitable for intensive sludge dewatering applications, delivering enhanced results.
d. Industry-Specific Optimization
Paper-Specific Formula: Specifically crafted for the intricate challenges presented by small fibers, lignin, and other compounds in papermaking wastewater, PAC achieves a decolorization rate surpassing 80%, optimizing paper mill operations.
Heavy Metal Capture Function: Expertly proficient in eliminating heavy metal ions such as lead and chromium through hydroxyl bridging, PAC achieves a removal rate exceeding 90%, ensuring safer and cleaner water.
Demulsification and Oil Removal Ability: Equipped with the capability to demulsify and separate emulsified oil in oily wastewater, PAC excels in addressing challenges faced in mechanical processing operations, enhancing oil removal efficiency.
